Physics Lab Report Ib Measurement

Physics Lab Report – Measurement Aim: To calculate, winning uncertainties into consideration, the uttermost and minimum possible values of the assiduousness of a woody block, copper wire and marble using the expression: compactness = Mass/Volume The volumes are calculates using a vernier caliper, a screw grass and metric ruler, and deracination of water respectively. The canaille are respectd using an electronic balance. Background: The vernier caliper has devil jaws which are to be closed tightly on the butt to be metrical. The centimeter and millimeter scratch to the left of the 0-mark of the vernier scale are read. To determine the 1/10th millimeter, the mark on the vernier scale which coincides with a mark on the main scale is read. The screw cipher postings objects to the 1/00th millimeter. In order to measure an object, the object is fit(p) between the jaws and the thimble is rotated using the ratchet until the object is secured. The prem ier significant figure is taken from the last graduation usance showing on the sleeve to the left of the thimble. The next ii significant figures are taken directly from the thimble by reading the mark which is directly opposite the main scale. To measure volume by displacement of water, a graduated beaker is variety with water. The initial level of water is noted.

The object to be measured is placed inside the beaker and the final level of water is noted. The fight down between the final and initial level denotes the volume of the object. The electronic balance measures the mass of an object. The device should be reset to nil before every readi! ng. Hypothesis: I predict that the perseverance of the wooden block will be less than guanosine monophosphate kg m-3 or 1 g cm-3 (the niggardliness of water) as it floats on water. The density of the marble and the copper wire, however, is greater than the density of water (i.e. it is greater than 1 g cm-3) as they buy the farm in water. Variables: There is no dependant or work variable in this experiment. All...If you want to get a gracious essay, order it on our website: OrderCustomPaper.com
